To all whom t may concern.'

Be it known that we, FRANK S'rnnrorr and l PAUL B. STREICH, citizens ofthe United States, and residents of Joliet, Will county, and State ofIllinois, have invented Vcertain new and useful Improvements inConveyers for Proofing Apparatus, of which the following is declared tobe a full, clear, and exact description.

lThis invention relates to proofing apparatus and morey particularly tothe conveyer which conveys the lumps of dough through the proofingchamber thereof. One form of proofing apparatus is shown and describedin our prior application for patent, filed by us on August 13, 1918,Serial No. 249,646 from which this application has been divided.

Proong apparatus of this character comprises an elongated proofingchamber in which travels an endless dough conveyer having buckets forreceiving lumps of dough Yand conveying them through the chamber for apredetermined interval and thereafter discharging them therefrom to besubsequently acted upon by other means.

The present invention has for its main objects to increase the capacityof the conveyer and to simplify and otherwise improve upon theconstruction of conveyers of this class. With these and other objects inview, this invention consists in the several novel features hereinafterfully described and claimed.

The invention is clearly illustrated in the accompanying drawing, inwhich:

Figure 1, is a vertical, cross section through a proofing apparatusembodying a simple form of the present invention; Fig. 2, is a viewpartly in plan and partly in section of a conveyer and side walls of theproofing chamber; Fig. 3, is an end elevation of one of the conveyerbuckets; Fig. 4, is a view partly in side elevation and partly invertical, longitudinal section of a fragment of the conveyer, the lineof section being indicated at line 4-4 in Fig. 2, and Fig. 5, is adiagrammatical view of a proofing chamber and conveyer.

Referring to said drawing, which illustrates a simple embodiment of thepresent invention, the reference character A, designates an elongatedproofing chamber and B, designa@ .the ifzlveyer which .travels throughsaid elongated proofing chamber. As in our prior application, abovereferred to, the proofing chamber may comprise upright frame members 26,horizontal, lengthwise extending fr, me members 27, secured thereto,vertical panels or walls 40, and top and bottom walls 3l. The side wallsmay be connected by cross members 29, to strengthen and reinforce thestructure.

The endless traveling conveyer B, comprises an endless belt 43, which istrained around a number of pulleys 46, mounted 52, supported by theframework of the proofing chamber. One or morey of the shafts are drivenby a suitable motorto travel at a low rate of speed. 'Connected withsaid endless belt 43, are the vdough receiving buckets 44, which are`arranged in pairs along the length of `the conveyer belt 43, one bucketof each pair being disposed at one side of the belt and the other at theopposite side thereof. Each bucket is formed with oppositely disposedears 55, 57, at the top of its side walls and the ears 55, of each pairof buckets are connected by a rod 53, which is secured in said ears 55,by set screws 56, threadedin said ears and bearing against the rods.Said rods 53, extend across the conveyer belt 43 and are rotativelysecured thereto by clips 54, which are bolted, riveted or otherwisesecured to said belt. In the ears 57, are secured short shafts uponwhich are journaled rollers 58, that travel upon tracks 59, secured tothe framework of the proofing chamber.

Obviously, the conveyer belt-may be of any suitable form of constructionand it is here illustrated as comprising a flexible band, and to providefor taking up slack which occurs in belts of this character, shortpieces 43a, are provided at intervals in the band which short pieces aresecured to the main portion of the band by belt fasteners 43h, and` saidshort pieces may be removed when the band stretches and the adjacent endportions of the band may be secured together by the belt fasteners.

upon shafts 49, journaled inbearing boxes It is to be observed that thebuckets of i .rollers .58: travel al@ .that the conveyer bei servesprincipally to move said buckets through the proofing chamber.

Said piv- 'otal connection also permits the buckets toLetters VPatent veyer belt permits the buckets to remain in an uprightposition, although the belt travels aroundthe pulleys, back and fort-hbe inverted byk dumping mechanism (not shown, but shown and describedVin our prior application) for dumping the dough at the discharge end ofthe machine.

More or less variation of the exact details vof construction is possiblewithout devparting from the spirit of this invention;

we-desire, therefore, not to limit ourselves to thefeXact forni of theconstruct-ion shown and described, but intend in the following .claims,to pointout all of the invention disclosed herein.

We claim as new and desire to secure .In an apparatus of the combinationwith an elongated proofing chamber, oppositely disposed tracks therein,j, Vandpulleys mounted therein, of an endless `traveling conveyer beltextending back and forth in said chamber and trained around saidpulleys, bucket supports projecting lfrom each side of the belt, clipspivotally connecting said bucket supports to said belt, and bucketsconnected to said supports and Ving rollers on their outer ends theclass described,
